Running Avocado with VMD device in Ci

Once you have your PR ready, Merge samirrav/DAOS-8161 branch to run the test in Ci
Ci has Two servers wolf-156/157 and single CN wolf-180 so you can run test with 4 daos servers and 1 client
Update the test file yaml file small.yaml,
- VMD stage has Two servers o remove any extra servers
- VMD stage has one client for now so remove other clients
- Replace the bdev_list with variable disk ID which will be replace by Avocado ["aaaa:aa:aa.a","bbbb:bb:bb.b"]

Follow example src/tests/ftest/nvme/health.yaml for running multiple servers from same branch samirrav/DAOS-8161.

Change the Tag in test python file For example small.py test was running with large so for VMD it has been changed to run with small VMD cluster

Server OS CentOS 8.4:

Right now we can not build and run from source so make sure to run test based on RPM
Remove the existing daos bin (Remove the path and lib OR delete the local daos/install folder)

Install daos rpm using the command :

sudo yum install -y daos-client daos-tests daos daos-server daos-debuginfo

Test code will be under so do cd /usr/lib/daos/TESTING/ftest/
Change the code in the below file

Server OS CentOS 8.3:

Installed the RPM on server and client (use the above yum command)- This is needed so avocado can run systemd
